.expect("Failed to read line"); 我们可以将这段代码编写为: io::stdin().read_line(&mutguess).expect("Failed to read line"); 但是,一行过长的代码很难阅读,所以最好拆开来写。当您使用.method_name()语法调用方法时,用换行和空格来拆分长代码行通常是明智的。现在让我们来看看这行代码干了什么。 ...

后一部分是这个方法(method): .expect("Failed to read line"); 我们也可以将代码这样写: io::stdin().read_line(&mutguess).expect("Failed to read line"); 不过,过长的代码行难以阅读,所以最好拆开来写。通常来说,当使用.method_name()语法调用方法时引入换行符和空格将长的代码行拆开是明智的。现在...
